Outline of Final Research Achievements

We made investigations on relativistic Fermi particle systems under strong external magnetic field, taking account of rotation, expansion, and such nontrivial geometrical effects. This research should have essential importance for theoretical understanding on relativistic heavy-ion collision experiments, internal structures of the neutron star, and table-top experiments with condensed matter materials. We pointed out that it is crucial to impose proper boundary condition on surface of a finite-size system in order to describe rotation effects correctly. Then, we explicitly demonstrated that the wave-functions are accumulated near the surface and they effectively respond to the magnetic field very strongly.
